They [the Sages] stated a major rule they with respect to Shabbat: [If] one [entirely] forgot the principle of Shabbat, and performed many Melakhot [constructive activities forbidden on Shabbat and festivals] on many Shabbatot, he is only liable for one Chattat [an offering brought to expiate sin]. [If] one was aware of the principle of Shabbat, but performed many Melakhot on many Shabbatot he is liable for [one Chattat] for every Shabbat. [If] one knew it was Shabbat and performed many Melakhot on many Shabbatot, he is liable [to bring a separate a Chattat] for every principal Melakhah. [If] one performed many Melakhot all of which stem from the same principal Melakhah, he is bound to bring but one Chattat.

They [the Sages] stated another rule: [If] one carries out on Shabbat something that is fit to be stored, of a quantity that is usually stored, he is liable for a Chattat. But [if] one carries out something that is not fit to be stored, of a quantity that is not usually stored, he is only liable if he was the one who stored it.

[One is liable if] he carries out a cow's mouthful’s worth of straw; or a camel's mouthful’s worth of pea-stalks; or a lamb's mouthful’s worth of grain; or a kid's mouthful’s worth of grass; or moist garlic or moist onion leaves [the size of] a dried fig; or a kid’s mouthful’s worth of dry garlic or onion leaves. And these cannot be added together since the [required] measures are not equal [for all materials]. [If] one carries out [any article of] food equal to [the size of] a dried fig, he is liable. And [food amounts] may be added together since the [required] measure is equal [for all food]; except for their peels, their pits, and their stalks; [likewise] their bran, or their coarse bran. Rabbi Yehudah says: Except as well the husks of lentils which have been boiled with them.
